High Performance Double Eccentric High Temperature Butterfly Valves With Lug Wafer End

 

TEKO double offset design and dynamic seat construction provides a reliable 100% bi-directional disc sealing. This unique construction meets the high demands of applications in which high performance butterfly valves are being used. TEKO high performance butterfly valves can be used for a maximum pressure up to 100 bars or a maximum temperature of 500℃. The high performance butterfly valves can therefore very well be used for applications, where rubber liner butterfly valves no longer can be used, due to their limited pressure and temperature range.

About double eccentric design

High performance butterfly valves, also known as double eccentric butterfly valves have stem which is mounted slightly out of the pipeline center and also behind the disc seat. This design leads to minima wear and low operating torques.

Main Feature of TEKO high performance butterfly valves

  • Flow way direction - slot on top stem indicates positive disc position
  • Mounting top flange - meets ISO 5211 pattern providing low cost near direct mount actuation capability
  • Extra long neck provides path for heat dissipation and allows space for insulation
  • Stem seal - self-lubricating PTFE V-rings prevent leakage to atmosphere
  • O-Ring - serves as first line of defense for stem leakage
  • Retainer cover - maintains seat integrity prior to installation, interchangeable with any seat option, standard surface finish is 125 - 200 AARH, compatible with both standard and spiral wound gasket designs
  • Retainer fasteners - stainless steel set screws provide ease of seat replacement
  • Over travel stop - integrally casted into body, prevents disc from rotating in wrong quadrant and damaging seat
  • Anti-static grounding - provided by stem ball at the very end of the stem shaft
  • Bottom flange cover equalizes pressure under shaft, eliminating piston effect at higher pressure
  • Blowout proof shaft - 17-4 PH stainless steel stem provides excellent strength, alignment and rigid support to disc
  • Easy-access parking gland provides means for packing adjustment even when direct mount actuation and insulation are utilized
  • Top stem bearings - top RPTFE/stainless steel self-lubricating bearings provide excellent stem support and shaft alignment
  • O-Ring - extra protection for leakage through body and seat retainer
  • Soft seat - one piece solid RPTFE static and dynamic seat design seals at both high and low pressures
  • Wedge pins - provide positive mechanical attachment of disc to shaft
  • Bottom stem bearings - bottom RPTFE/stainless steel self-lubricating bearings provide excellent stem support and shaft alignment
  • Shaft retainer provides positive stem retention
  • Bottom packing - the lower shaft utilizes seal in the body to prevent external leakage and simplify valve maintenance
  • Soft seated standard valves are suitable for vacuum service to 20 microns
  • For dead end service
